hi everyone.
i have to design a uwb antenna with bandwidth ranging from 3.1 ghz to 10.6 ghz using fr4 substrate.
i have designed many antenna according to calculations using formulas yet none of my results stand true..consider me a noob and please help me in this regard..thank you

P.S. Im using hfss 13 for simulations

so nobody wants to help me??:(
 

Hey,

It's not necessary that you get the desired results with the exact parameters obtained by the equations.
You have to play around with the dimensions for the adjustment.
 

ok i am done with achieving the bandwidth part of the antenna..
now i seek ur help in notching the band from 5-6ghz..
what should be my approach?? any techniques or formulas??
thanks..:)
 

That's good. In order to achieve the band notch characteristics various techniques including
use of tuning stubs, shaped slots and parasitic elements can be utilized according to the
requirements of your design. I suggest you to go through some research papers than you will be
able to apply any of these techniques.
 

i have tried to apply various designs but im unable to notch 5-6ghz band..
every method that i have applied notches 4-5ghz band..
may i upload the design so that u cud help me in a better way??
 

Your design has been simulated in HFSS 13. Unfortunately i don't have the same version therefore
i will not be able to work on it.
